My usb wireless adapter module is ath9k_htc , I can find it with lsmod .
But when I plug the adapter , it does not work .
Even the light of adapter does not flash .

At that time I can use u-disk and usb keyboard .
My kernel is configured by manual , not with genkernel .
What is the matter ?
The adapter can work under ubuntu12.04 amd64 kenel 3.2.0-35.
My gentoo kernel is 3.6.11.
